The biggest for me is a Glock 19 and I rarely carry it. The one I carry the most is my LC9s Pro. It is very comfortable with it's tapered slide, smallish grip and rolled edges I clip in the waistband of my pants with a Techna-clip and literally forget it's there. I carry a Sig P938 some too but it's not as comfortable as the the Ruger. The LC9s is a well thought out pistol.
